To. all whom it may concern.'

Be it lmown that we, Moines Einer and JOHN M. DANZIG, citizens of the United States, and residents of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Printing Apparatus, of which the following is a specification.

This invention has reference to a printing vdevice that can be used as a hand printing device and can also be utilized on a stand of a paper roll to print on the paper as it is unrolled.

The invention has for its object the improvement of devices of this character in numerous important respects.

A printing apparatus in accordance with our invention is made so that the ink coated working parts are well protected from dust and also `from coming into contact with and' soiling the fingers or other objects, this protection being afforded by a removable shield, the removal of the shield making it possible, without further disturbing the device, to inspect the printing and inh'ng elements and to ink the rollers, and to give the working parts any attention or repair which may be needed. l

rllhe printing and inkin devices are held in a frame, which is removably secured to a bracket, such bracket being adapted to be secured to a paper roll standard or the like,A`

and to hold the device in proper relations therewith. When removed from the bracket, the frame, with its printing devices, can be used as a hand printer, it being provided with a handle suitably disposed for convenient and easy manipulation of our improved device when used for hand printing. We also preferably provide a spring or springs, which act to yieldingly press the printing device' against a paper roll when it is used in this connection, the springs being easily disconnected to permit the removal of the frame from the bracket. The springs are made adjustable in order to vary the tension, the adjustment being possible without removing the frame from the bracket.

One form of apparatus involving our invention is illustrated inthe accompanying drawing, inwhichv Figure 1 is a side view of a printing device attached to the cross-bar of a paper roll standard, only a part of the roll and standview showing one of the inking rollers and part ofthe type roll. Fig. 5' is a detail'view lllustrating one of the side pieces of the bracket. Fig. 6 illustrates the apparatus as used for hand printing.

The device can be used in various situations, but in Fig. 1 we show it attached to the top bar 10 of a standard 11 which holds a paper roll 12 from which thev paper is Y pulled olf in the usual way, the roll being.

rotated when .the paper is pulled.

Our improiied .device comprises a clamping bracket `13 having a neck 14, with an ear 'l5 on one end, the ear being provided with suitable fastening means, as a screw 16, to

draw the shoulders 17 of the side pieces 18 against the top bar 10 to fasten the bracket in place thereon. The shoulders 17 may be corrugated, as shown at 17', to assure a strong hold of the clamping bracket on the v standard.

@ur improved device further comprises a suitable frame to hold the printing roll and the inking devices, .this frame being preferably made up of side pieces 19 and cross bars 20 and 21, the frame so constructed .be ing light and strong.

rlhe bracket and frame are removably connected together' by means of a pivotal connection which is readily removable. As shown, the side pieces 18 of the bracket and the upper ends of thc side pieces of the frame are perforated to receive a rod 22 which has a fingerpiece 23on one end and has its other end screw-threaded as at 24. which end screws into the side piece 18 of thevbracket to prevent accidental withdrawal of the rod 22.

Mounted between the side pieces 19 of the frame are the rollers 25 and 26, which rollers are covered with suitable material 27, preferably absorbent material such as felt or cloth, the material being supplied with ink and such rollers acting as inking rollers, one of them, 26, directly contacting with the type roll 28, and the roller 25 being in contact with the roller v26. The printing roll 28 is preferably made of wood and has a strip or plate 29 suitably fastened to its periphery, in the form shown such fastening l the coils in place.

being made by tacks 30. o face 31 of the printing roll 28 1s mked by being brought into contact with the inking surface of 'theroll 26 ateach revolution.

To insure the traction of the printing roll on the roll of paper it is preferably pressed downward by a yielding element, usually a spring, applied to the-frame thereof, the form illustrated showing a spring 32 on each side of the frame, these springs having their 'ends resting on studs 33 on the frame side pieces, the studs having heads 34 to prevent'the springs'from slipping off. The upper ends of the springs 32, which are usually made of wire, are formed into coils 35 surrounding screws 36 with washers 37 on them. The wire at the ends of the coils is bent inward as at 38, the bent over ends 38 iittingl into any one of a series of holes 39 on the sideV pieces 18 of the bracket 13. The holes 39 are arranged concentrically about the screws 36.' The tension of the springs can be quickly changed, if this becomes necessary, either through reduction in size of the roll of paper, or by weakening of the spring by unscrewing the screws 36 far enough to permit the withdrawal of the ends 38 from-the perforations in the side plates 18 and placing them in other holes 39 to give the required tension, after which the screws 36 are again screwed up to hold This adjustment is possible without removing the frame .from the bracket.

On the frame is a suitable shield 40 formedto cover the inking devices and the printing roll, the shield shown having its front end 41 bent intof a hook-shaped strip which fits over the rod 22. Shields of other form than that shown, and other means of detachably securingl the shield in place may be used.

On the lower part ofthe frame, usually 'on the cross-bar 21, is a handle 42, by means of which the frame is manipulated when it is used as a hand printer, and such handle is preferably disposed at an angle making its use for such purpose most convenient, and also to be out of the way when the apparatus is attached to a paper roll holder or the like. l

The drawing shows, in Fig. 1, the parts assembled to print on the paper of the pa- `per roll when the rolly is rotated. When the device is to be used as a hand printer for The printing surprinting paper sheets or bags, or other material or objects, the shield 40 is removed and then the rod 22 is unscrewed and withdrawn. This leaves the frame free to be used as shown in Fig. 6. The handle 42 is usuallydisposed at an obtuse angle to the sideieces 19, this permitting the most comforta le use of the device as a hand printer andalso preventingrundue projection of the handle when the ame is fastened in the bracket. l

To ink the rollers 25 and 26 when the device is installed on the standard 11, the

vshield is removed by simply lifting it from engagement with the rod 22 and the rollers and the type roll 28 are exposed.

It is to be understood that the scope of our inventionis defined in our claim and that we are not confined to the precise ccnstruction shown and described, but that changes and modifications may be resorted to within the scope of our claim and without departing from our invention or sacrificing the advantages thereof.

' Having thus described our invention, we claim:
